The firmware update for the EV NS (product-ID C26) from 1.27 to 1.28 was offered in the VRM. After I initiated the process, it was no longer possible to reach the station via the VRM portal and the previously assigned IP. All attempts to communicate with the GX device failed. After many unsuccessful attempts, it turned out that it was only possible via a Bluetooth connection using the Connect app. The station could then be reached via the web interface by setting it to Accesspoint and via its default IP 192.168.0.3. Nevertheless, it was not possible to enter the necessary network data - any configuration attempt with the settings of the home network failed. The last resort was to restore firmware 1.27. . After that, all connections, data, settings etc. were back. Is the fault with me?
